EXHIBIT <br />22. Laboratory data from the 2nd Quarter 2011 provided to the Division by Peabody establish that effluent <br />from Outfalls 002 and 004 was analyzed for potentially dissolved selenium using two different analytical <br />methods, each with a different corresponding PQL. The laboratory data sheets establish that the analysis <br />of Peabody's effluent for potentially dissolved selenium using the Standard Method 3114 B, AA -Hydride <br />had a corresponding PQL of 5 ug/1 and the analysis of Peabody's effluent for potentially dissolved <br />selenium using the EPA Method 200.8 ICP -MS had corresponding PQLs of 0.3ug/1 and 0.5 ug/l. <br />Peabody's laboratory data from the 2nd Quarter 2011 for potentially dissolved selenium analysis at Outfalls <br />002 and 004 is summarized below: <br />23. Peabody's discharge monitoring reports for the 2nd Quarter 2011 (April I" through June 30d') reported the <br />following effluent concentration data for potentially dissolved selenium as compared with the effluent <br />concentration data from the analytical method that measured the lowest detected limit for potentially <br />dissolve selenium: <br />Peabody Sage Creek Mining, LLC <br />f/k/a Sage Creek Coal Company, LLC <br />Notice of Violation/Cease and Desist Order <br />Page 6 of II <br />
